how to find the reasons when some mistake happened?

(OP)
I'm new to abaqus, and studying now.
Everytime, when I write a code, there is something wrong.
Could somebody help me what's wrong with these code? How to check what's wrong when it happened? To see the status file? thanks so much!

RE: how to find the reasons when some mistake happened?

Best places to look - the .sta (status) file and the .dat file.

I've just datachecked your deck in 6.6-1 and I get an "aborted with system error code 144" in the log file.  Looks like you'll need to speak to ABAQUS support on this one (unless anyone else can decipher the error code smile

Regards

Martin

RE: how to find the reasons when some mistake happened?

I would first check the .dat file. If you seach for error. the following have shown in the .dat file

 PROCESSING PART, INSTANCE, AND ASSEMBLY INFORMATION
   *******************************************************


 ***ERROR: in keyword *MATERIAL, file "test.inp", line 18: OdbError: Tabular
           data for at least one option or suboption            has either
           blank or zero valued row(s).
 ***NOTE: DUE TO AN INPUT ERROR THE ANALYSIS PRE-PROCESSOR HAS BEEN UNABLE TO
          INTERPRET SOME DATA.  SUBSEQUENT ERRORS MAY BE CAUSED BY THIS OMISSION

Then if there is no error in the .dat file, usually they are due to typo and very easy to debug.

If there is no error in .dat but error in .msg. that is quite a usual case, usually meaning the FEA can not convert a solution. This is harder to debug as so many reason is behind it. But the error message in the .msg will give you some cludes.


In your case. I belive there is a space where you define the material.

*MATERIAL,NAME=AA5152O3
*DENSITY
2700E-12
*EXPANSION
1.0E-8
*ELASTIC
69E4, 0.31
*PLASTIC
113.3,0.0000,20
....  <-------

delet that line will debug one of the error

RE: how to find the reasons when some mistake happened?

Yeah, I commented that line out, but it fails with the error code 144.
